The article discusses the valorization of the knowledge of farmers and family farmers in the conception of differentiated approaches in science teaching in schools in the countryside. For this, we studied the equipment used by farmers in the production of cassava flour as the levers and identified the mechanisms of the presses. Participant observation and semi-structured and open interviews were conducted with three families in the municipality of Senador José Porfírio, Pará. From the ethnophysics approach, it was found that they construct the presses manually, adapt and improve the operation of the levers, according to the progress of their activities. This traditional knowledge is passed down from generation to generation, via orality, observations and lived experiences. Farmers explain the mechanisms in such a way that they relate the objective to be achieved and the effort to be spared by choosing the dimensions, shape and types of materials for the construction of the press, without having theoretical knowledge of physics. This knowledge can be used in science classes, from observation and interviews to parents or community, made by the students themselves, making the detection of the lever mechanism in various equipment, tools or movements of daily life, identifying the forces involved and how it could improve them.

The physics teaching still finds many obstacles in basic education, mainly because of the strong resistance that we find within its methodologies, still centered in the didactic book and the memorization of formulas and laws. This manuscript aims to present the results of the strategies of Simulated Jury and Brain Storm developed in a Countryside Education Degree (emphasis in Natural Sciences), specifically at Fundamentals of Physics III in two classes of the 4th Period, in the countryside Of Paraense Amazon. In one class we used the strategy Cerebral Storm and another strategy was the Simulated Jury, the Electricity content. The analyzes were made based on the reports of the students in the class and notes made by the teacher/researcher. These developed strategies allowed the rupture of the stereotypes presented among the students about the methodologies used by their teachers in teaching Physics contents, which was based on traditional expository classes, and with the strategies used they realized that they can approach the contents of and, above all, led them to a critical reality understanding in which they are inserted.
